Hi @salman20054,

Are you editing the Smarty templates? If so, you probably need to properly escape { and } characters, by using {ldelim} or {rdelim} or enclosing the whole thing in {literal} tags. For more on Smarty syntax, see https://www.smarty.net/.

just for a try, i had inserted the code in line 20 in headerhead.tpl,
after having a try in front end i opened the file to remove the code/alter the code but the code which i was pasted is no longer available in it.

how can i rectify this error.

issue had been solved by replacing old back files.
